3D printing medical equipment

For the last week and a bit I have been 3D printing a variety of protective equipment for healthcare in the UK. I found a group called 3Dcrowd that have been coordinating an effort to supply face shields to healthcare across the UK. You can visit their website if you want to request face shields for your GP surgery or hospital or sign up as a volunteer. They have chosen to focus on the Prusa RC3 face shield (when the group started it was the RC2 version) which can be found here . I set up the files on my Prusa i3 MK3S using a 0.3 mm layer height and the first prints came out great, apart from the arms of the frame which kept detaching from the buildplate and causing messy layers on the pegs for the elastic, so to fix that I came up with some brim ears in PrusaSlicer. Prusa RC2 frames printed. Prusa RC3 with added brim ears. I was lucky enough to have two kilos of PETG donated to the cause by the lovely Tim at 3DFilaPrint in a nice translucent black colour. The prints
